The class member variable "link_thresh" in class Env is never assigned and always set to default 0.
In the constructor of class Env , the passed parameter has the same name "link_thresh". Although this parameter "link_thresh" is set to 0.5, it is not assigned to the class member variable "link_thresh", since the later is often used in other codes.
The same cases to other class member variable "lt_min_deg" and "gap".
